Research On Problem Solving Teaching Of Primary School Mathematics From The Perspective Of Computational Thinking

In the era of big data,computational thinking has become an educational problem that countries gradually attach importance to.Like reading and writing,it is regarded as the basic ability of students in the 21st century and plays an important role in individual development.Mathematics is an important part of human social civilization,and mathematics literacy has become the basic literacy that individuals must possess.Among them,problem-solving ability is an important embodiment of mathematics literacy,and its cultivation has been widely recognized by mathematics education circles.From the perspective of computational thinking,there are many common points in solving mathematical problems.Therefore,studying the problem-solving teaching of primary school mathematics from the perspective of computational thinking can not only promote the relevant research of computational thinking,but also have important theoretical and practical value for the problem-solving teaching of primary school mathematics.In the research process,the methods of literature research and case analysis are adopted,which mainly solve the following three key problems:first,the basic process of computational thinking in solving mathematical problems;Secondly,on the premise of grasping the basic process of problem solving of computational thinking,this paper analyzes the process application of computational thinking in the teaching of mathematics problem solving in primary schools;Thirdly,it puts forward some suggestions on integrating computational thinking into mathematics teaching.This paper constructs the research and development of computational thinking by means of literature research,and explores the process of computational thinking from the existing problem-solving model;Then,using the method of case study,this paper explores an example of solving mathematical problems in primary schools under the mode of calculating thinking problem solving.Based on the case analysis,it is proposed to constantly modify and improve the mathematics teaching process in the application practice of school education,so as to provide feasible solutions for school education and curriculum suggestions for teachers' teaching.The research results mainly include:1.The problem solving process of computational thinking is divided into three stages:understanding problems,exploring problems and solving problems,among which understanding problems include abstract problems and decomposition problems;Inquiry questions include planning scheme and implementation scheme;Problem solving includes summary evaluation and optimization transfer,which correspond to the five thinking abilities of computational thinking respectively.2.Starting from the problem solving of computational thinking,this paper discusses the applicability of computational thinking in the teaching of mathematical problem solving in primary schools.By using the abstraction of mathematics in the teaching process,it builds up a general understanding of mathematical rigor in logical reasoning,and establishes a broad understanding of mathematical application in the modeling process,so as to develop students' problem solving ability and computational thinking ability.3.Based on the research and analysis,this paper explores the application of computational thinking in primary school mathematics problem-solving teaching from two dimensions.Firstly,it points out the abstract influence of computational thinking on primary school mathematics concept teaching and proposition teaching,changes the previous teaching concepts and attaches importance to the formation process of knowledge.Secondly,in the programming education,according to the cognitive characteristics of learners,we should make effective use of information technology and carry out "Internet+education".
